- W4311877586 abstract "Based on the materials of scientific monitoring at the Cherepetsky reservoir in the Tula region, the composition of the fish population at the present stage is given. The places of mass spawning and wintering of the main fish species were also identified. Wintering pits are located in the dam part of the reservoir, as well as downstream along the watershed dam. The places of mass spawning are located in the upper (river) part of the reservoir, as well as in the area of the village of Tsentralny. The materials were the results of hydro acoustic and grid surveys at the Cherepetsky reservoir in 2021. Ichthyological studies have not been carried out on this reservoir since 2013. According to the results of research surveys in 2021, with the use of the order of the set nets, a small variety of ichthyofauna was recorded — eight species of fish. According to the research results, a reduction in the species composition of fish was recorded. Natural fish productivity decreased from 140 kg/ha to 90 kg/ha. Reduction of natural fish productivity and absence of thermophilic fish species in catches (white carp, white and black cupids) most likely it is connected with the modernization of the Cherepetskaya GRES. Due to the lack of industrial fishing at the Cherepetsky reservoir, the exploitation of aquatic biological resources can be called irrational.To improve and develop the water body, it is recommended to carry out reclamation measures, the introduction of herbivorous (white and black Amur) and predatory fish (pike) and their protection." @default.
